串联同步开关电感(Series Synchronous Switch Harvesting on Inductor,S-SSHI)电路输出功率高整流电压范围窄,而同步电荷提取(Synchronous Electric Charge Extraction,SECE)电路则输出功率低整流电压范围宽.提出了一种基于S-SSHI和SECE混合的压电阵列能量俘获接口电路,以实现整流器峰值输出功率和最佳整流电压范围之间的平衡.所提出的电路去除了整流桥结构,而采用简单的无源峰值检测器设计,且可以在任意相位差(0～2π)下从多个压电换能器中提取能量.仿真和实验结果表明,所提出的电路具有较高的输出功率和较宽的整流电压范围,与多输入全桥整流器相比,最大输出功率提升了3.04倍.
Hybrid S-SSHI and SECE Based Energy Harvesting Circuit for Piezoelectric Array
Series Synchronous Switch Harvesting on Inductor( S-SSHI) circuit has a narrow rectified voltage range with high output pow-er,while Synchronous Electric Charge Extraction(SECE)circuit has a wide rectified voltage range with low output power. A piezoelectric array energy harvesting interface circuit based on the combination of S-SSHI and SECE is proposed to achieve the balance between the peak rectifier output power and the optimal rectified voltage range. The proposed circuit removes the rectifier bridge in favor of a simple passive peak detector design,and can extract energy from multiple piezoelectric transducers with any phase difference ( 0-2π) . Both theoretical analysis and experimental test show that the proposed circuit has a high output power and a wide rectified voltage range,and the maximum output power is 3.04 times higher than that of the multi-input full-bridge rectifier.
